Video Shows suspect Fleeing the Scene of Fatal Queens Subway Shove

A madwoman last night pushed a stranger onto subway tracks in Queens, where he was killed by a train, police and witnesses said.

It was the second such nightmare in less than a month.

The unsuspecting victim was waiting at the elevated 40th Street station of the 7 line in Sunnyside at 8 p.m.

“This lady, she just pushed the guy on the tracks. Then she ran away. I was screaming and closing my eyes,” said witness Tenzing Tegeng, 21, one of five people on the platform.

“I knew he was gonna get hit by the train. That’s why I closed my eyes. I didn’t want to see it.

“I could see him, and I could see a train coming. And I couldn’t do anything. I was so helpless. He was trying to get up. It was so fast,” she said.

The assailant said nothing as she pushed the man to his doom, a law-enforcement source said, adding, “He didn’t even know she was there.”

The man was struck by a Flushing-bound train.

“He looked shocked. He didn’t scream,” Tegeng said.

The victim’s mangled body was wedged underneath the second car.

Cops were hoping to obtain the victim’s identity from his laptop and wallet, which were found at the scene, the source said.

Witnesses told investigators that the woman had been sitting alone on a bench, mumbling, but sometimes getting up to pace back and forth.

“She was acting weird and crazy,” the source said.

After the attack, she fled down the stairs to Queens Boulevard.

“She was so fast. I was like, ‘Stop the lady!’ ” said Tegeng, who chased the woman with several others.

Tegeng did not hear any arguing beforehand. Others also reported no interaction between the two.

“My customer came in out of breath saying, ‘My God! They pushed a man in front of the subway.’ It’s a shame this happens right after Christmas,” said local pizzeria owner Giovanni Briones.

Video cameras from his eatery show the suspect fleeing south down 40th Street toward 47th Avenue.

She was described as 5-foot-5, Hispanic, weighing about 190 pounds and between 20 and 25 years old. She has short, dark, curly hair.

Meanwhile, an hour later, a Good Samaritan kept a disturbed man from leaping in front of a Queens-bound E-train at the 50th Street Station on Eighth Avenue in Midtown — even though the would-be jumper then assaulted him, said MTA officials. The brave bystander wasn’t seriously hurt.

Last night’s horror was a chilling echo of an incident on Dec. 3, when drifter Naeem Davis, 30, allegedly shoved Queens dad Ki Suk Han, 58, into the path of a Q train at the 49th Street station in Manhattan. Davis is being held on murder charges.
